IMPROVEMENT IN CANDLE-MOLDING. MACHINES.

The Schedule referred to in these Letten Patent and making of the same.

1'0 all whom it 'may conce/rn Beit known that I, JOSEPH WALns, of thecity,

county, and State of New York, have invented a new and improvedCandle-Molding Machine; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable othersskilled in the art to make and use the same, reference being had to theaccompanying drawing forming part of this specification.`

ing apparatus used for receiving the candles when lifted out of themolds, holding them till the nex batch is molded, and then removingthem.

It also consists in certain details of construction in relation to theapplication of the molding-tubes to the supporting-plates, and to theintroducing and drawing oli' ofthe 'water employed for cooling themolds, all as ranged it is necessary to employ a complete machine foreach size it is required to make; consequently, the machines being quiteexpensive and there being'many different sizes required, the manufactureof candlesinvolves the investment of a large amount of capital iumachines, much of which I propose to save by constructing the machinesso that they may be used for diereut sizes by slight changes being made.

In respect to the general arrangement of the machine, it is similar toothers now in use, and need not therefore be described in its mainfeatures, which arel well understood. The rst part of my inventionconsists in the employment, with the piston-rods or pnshers A and themold-tubes B, of two or more caps, 0,'according to and P of the boards KL M, will be separated for rethe number ot? dilierent sizes of candlesitis desirable to make in one machine, which caps are detachably As the.candle-molding machines are at present ar;

connected to the pushers, and are to be employed one at a time with.each piston, being of different sizes, the smallest being of such sizethat when on the piston it will drop to the lower end of the mold, andfit in it there-so-as to close it to hold the melted substance formaking the candles ofthe largest sizes.

The cap ofthe next greater size will be so as to fill themold, say, attwo-thirds the way'down at G1, and stop there forl making shorter andlighter candles, and another size may be so las to lodge, say, half waydown, as at O2, and make still shorter and lighter candles.

As many different sizes may be employed as required, and they will allbe adjusted so as to produce, by the lling of the molds above them, theseveral standard .weights of candles, respectively.

These caps lare made in cast metal, inthe form oi' a cup, with internalscrew-threads, and they are screwed on the upper ends'of the pistons,'asshown. They have a small hole through the bottom at the center, for thewick E to bedrawn up through them and the hollow pistons, as in othermachines.

" In order to pack around the wick tightly to preventthe meltedsubstance from escaping through these holes, Ipropose to introduce asott India-rubber disk, F, with a central hole for .the work, betweenthe bottom of the cap and the top of the piston, as shown, for pressingsnugly against the wickby being screwed in tight to close the passage,but allow the wick to be drawn up, which it will do by reason ofV thesoft and yielding nature of the material.

As the pistons will not fall so lowwhen the large capsV are used, theboard G, by which they are lifted,

through the medium of the racks H and pinions I,

will bea'rrested sooner in the downward movement.

The improvement in the clamping apparatus for re-` ceiving and holdingthe candles after having been lifted out of the molds is as follows:l

The three boards or plates K L M are divided into three parts, N O P,and connected to end boards Q Q l Q2, similarly divided, and hinged atthee top, as shown at R, the middle pieces Q1 being arranged on the topof case S, so that the other parts on each side of them may swing towarda'nd fro'm them for opening and closing the holes-T, for the candleswhich are formed by the semicircular grooves in each of the parts alongthe wires on which the said boards are divided, which holes arecoincident with the molds;-

The end pieces Q and Q have rods U 'jointed to them, which rods arejointed together at V, being of such-length that, when thel joint V-ismoved down into the right line connecting the joints of the said rodswith the said pieces, the latter, with the parts N ceiving the candles,the partsofthe board K being opened Ythe greatest amount, while those ofboard M will open but little, but the holes T in these being madelarger, will insure the proper reception ofthe candles therein.

W represents endless elastic bands of any kind, connected to thepivots-by which the rods U are -jointed to .the boards Q Q2, Aso thatthey will be stretched when the rods are moved down to open the clamp,

but when the joints Vare moved above the right line Y the molds asshown, the one, a, being smaller, so as to pass through the hole forlbreadily, and Asecuring them into the said plates.

This plan isrrnnch cheaper and simpler than the present mode ofapplying'anges or collars to the molds fortbe upper sides of the platesand clamping nuts on the molds below.

4The vspace A', between the plates X, is in practice alternately filledwith steam for heating the molds to the proper condition for receptionof the melted tallow and cold water for solidifying the same after themoldshayebeen filled. f' a Now, in making yshort candles according to myabove-mentioned plan, in these long molds, it will not be necessarytodraw the water all'out of the said space for heating the molds, but onlyso far down as the molds are filled. I therefore propose to employ, inconnection withthe pistons and caps arranged as described for makingcandles of different lengths, a glass 'or otherl transparent gauge-tube,B', arranged with the said space as shown, for indicating when. thewater has been sufficiently drawn out, and thereby economizeconsiderable time and water.

Having thus described my invention,

I claim as new and desire to secure by Letters Patent- 1.- Theemployment, with the molds and pistons, of

length of the molds, for making candles of different sizes in onemachine, all substantially as specified.

2. The combination, with tbe caps C and pistons A, of the elasticpacking-disks F, substantially as specitied.

3. The divided plates K L M of the clamp, having the semicircularnotchesfor clamping the candles con nected to the end pieces Q, Q1, and Q2,which are hinged together and provided'with the jointed rods U and theelastic bands or springs, all substantially as specified.

X bythe screw-threaded portions ab, substantially as specified. y V

A 5. The application, to the cooling and heating-tank of avcandle-molding machine, arranged for making different sizes, as hereindescribed, of the glass watergauges B', substantially as specified.
